I don't see much difference in the short term if it is a yes or a no vote. There is going to be financial carnage because even the yes vote will have to have at least 50% forgiven of the total debt other wise Greece is in a much worse position.
Greece cant even pay the interest on its current loans.
If the vote is no then there will be a financial shit storm as well but it will be short term and not forever as Greece will be instantly out of debt full stop.
The difference:
Yes vote poverty for 3 or 4 decades, loss of sovereign government.
No vote poverty for 1 decade at the most, sovereign government remains.
Have a look at the precedence set by Hungary and Iceland.
Then take a look at Italy, Spain and all the other small EU countries.
